. .MEANS mn CONTROLLING THE PULP- STRAlNER DRUMS 0F PAPER-MAKINGMACHINES."

To an" why???) it may concern/r Be it known that I, MiARCELLAMORT, acitizen\ of France, residing at Paris, in the said Republic, haveinvented new and useful Improvements in Means for Oo'ntrolling'thePulp-Strainer Drums of Paper Making Ma.- chines, (for which a" Frenchpatent, No. 362,996,..of'Februai'y 5, 1906, has been Obtained,) of whichthe following is a specificat1on.

This invention relates to improved means for controlling thepulp-strainer drums of paper-making machines, whereby two movements canbe communicated to them, one-a shaking or shogging movement, which im'parts to the drum a displacement of afew millimeters in the verticaldirection, the other a rotary inovement a consequence of the first,which imparts to the drum a very slow rotary movement of only a fewrevolutions per minute.

The annexed drawings represent by way of example, Figure 1, an end view,partly broken away, of an ordinary pulp-strainer drum of a paper-makingmachine provided with the controlling means forming the sub ject of theesent invention; Fig.2, an elevation of t e same, partly in longitudinalsection, taken on the line as y of Fig. 1'; Fig. 3, a plan of the same,partly broken away; and Fig. 4 a detail of one of the devices servingfor working the machine.

The same reference-numerals indicate like parts throughout the figures.

1 is a pul -strainer drum consisting, as usual, of a j ac et or casing2, supported at its ends by two metal heads 3 4, each having a flange 56, similar to the rim of a pulley that is to say, each is capable ofreceiving a strap 7 8, placed as shown at 9 1O 11, and the points ofattachment 11 12 of which are constituted by means of feet forminggrippers.

' At'9 13 the straps are connected to theends of two iron arms 14 15,both of which are keyed on a shaft 16. By causing the ends of these arms14 15, pivoted on the shaft rection. .5

centric 20, forming part of a driving-shaft 2-1, which is set in motionby means of a belt passing over a stepped pulley 22, therebyenvablingthe speed to be'varied at will, soas to obtain a' number, also variable,of shakings or shoggings of the drum- These shakings or shoggings arerendered sharper'"'and more energetic by the addition on each side ofthe drum of metallic stops or abutments 23,

placed immediately below each strap. As these stops or abutments arefixed and as the straps are capable of extension ,the feet 1 1 12 arenot fixed, but are each connected to a' screw-rod 25 26, capable ofbeing raised or loweredby' means of a hand-wheel 27 28, forming a nut[The travel of the drum can therefore be regulated by causing it to fallfrom a greater or less height back onto the stops or abutments, therebyobtaining all the desired effects-viz., beatingswithout shock, beatingswith shock, strong or weak, or even immobilityr The rotary movement ofthe drum is effected intermittently each time this latter is raised bythe two straps. It is, however, the consequence of this rising movementand can, in fact,,only take place as long as the straps are drawn by oneend only, because if they were drawn by both the r ends the drum wouldalways fall back to the same place and there would be no rotarymovement. This movement is, moreover, proportional to the-' necting-rod18 by bolts 30 31. At its upper end the connecting-rod 18 is jointed tothe lever 17 by means of a hemispherical brass piece 34,, traversed bythe comiectingrod,

which is screw-threaded at its end and is held by means of a nut and alock-nut. The piece '34 rests in a recess formed in the end of the lever17, which is bored to allow the connecting-rod 18 to pass through.

The shaft 21 is carried in two )lummer blocks, one of which is placed onthe side at 47 and carries two pairs ofbearing-blocks fixed on the twofaces of the frame 35 at 36 37 38 39. The other, also fixed on theframe, sustains the displacements of the shaft throu 'h the interventionof the rings 40 and 41.

The shattll may be placed in the direction of the axis 42 43 or in thedirection of the "axis 44 45. In this case, it is carried in twoplummer-blocks resting on iron chairs.

When two strainers are arranged tandem, the shaft 21 may be replaced bya shaft carrying two eccentrics at 20 and 46.

The annexed drawings represent other constitutive parts of: ordinarypulp-strainers for' paper-making machines; but as these arts do not inany way relate to the present invention they are not described hereinand consequently are not numbered.

1- claim Means for controlling the pulp-strainer drums of paper-makingmachines, whereby two movements are communicated to them,

one a shaking 0r shogging movement which imparts to the drum a'displacement of a few millimeters in the vertical direction, the other arotary movement which imparts to said drum :1 very slow rotary movementof only a few revolutions per minute, said means consisting ofcarrier-straps for the drum, one of the ends of which is fixed while theother is capable of receiving, at will, reciprocating movements oftraction of variable amplitude, whereby the shakings or shoggings of thedrum and, consequently, a slight rotary movement of this latter areefiected.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
